Actual blog post.

Great accomplishment. I think we all knew it must happen like this but it's great to see real world results.

I think this is probably actually the most useful part of the post:

Increasing productivity: Safe Coding improves code correctness and developer productivity by shifting bug finding further left, before the code is even checked in. We see this shift showing up in important metrics such as rollback rates (emergency code revert due to an unanticipated bug). The Android team has observed that the rollback rate of Rust changes is less than half that of C++.

I think anyone writing Rust knows this but it's quite hard to convince non-Rust developers that you will write fewer bugs in general (not just memory safety bugs) with Rust than with C++. It's great to have a solid number to point to.
